IMPROVEMENT IN EXPRESS-WAGON.

To ALL WHoM 1T MAY coNosnN:

Be it known that I, T. W. PORTER, of Boston, in the county of Suifolk, and State 'of Massachusetts, have invented anewl and useful Improvement in Exp'icss-lllagons'; and` I do hereby declare that the following-is a full, clear, and` .exact description of the Aconstruction and operation of the same, reference being had to the accompanyingl drawings, making a part of this specification, in which Figure lis a top or plan view of theundcr-work.

Figure l2 is a perspective View ofthe front axle.

Figure 3 is a. vertical transverse section, taken on line X Y.

Figure 4 is an under side perspective view ofthe perch and axle-coupling.

Figure 5 is a verticalsection, taken on line V W. i

Figure 6 is a. perspective v iew of the tail-board and adjustingfdevicc.

Figurel'l is a horizontal section, taken ou line T U; and

Figure 8 is a vertical section, taken on line R S.

Similar'letters of reference indicate corresponding parts iu the several figures.

vThe nature of my invention consists in an improved coupling for the head-block and forward axle, obviating holes through theiaxle and stock, for either the king-bolt or bolts attaching the rocker and axle-plates, and in forming these platescheaply and indestructible; also in an improved methodvof attaching the perches to the axle andy head-block, and in an improved .tail-board, and vdevice for adjusting and securing the same.

In the drawings, A represents the forward axle, B the hind axle, and C and C the perches; D D the perchstays, and E the head-block/ a is the rocker-plate, which is formed with straps extending along the under side ofthe perches, and are united wby the bar bfwvhile a central tail or bar c extends from the centre'ot' theplate to bar b. i In the tail c, just in rear ofthe head-block, is a recess, inwhich the circular disk or die d lits, aS shown. Upon the lower side'of disk dis a flange, which extends through a hole in the tail c, as shown.. Through a central hole in disk cl the king-bolt c passes. A packing of rubber, g,is placed between the kingbolt and the capf, to obviate lrattling. The'capf, which corresponds in outl'ine to tail c, is secured theretoT by screws, as shown. The die d may be formed with a slight projection to lit to a corresponding recess in the tail c, to prevent the die from being revolved by the rotation of the king-bolt, and it may be formed of hard; metal, to prevent its being rapidly worn by the motion of theboltJ/L is the axle-plate, with recesses or panelsin its face, in which are embedded, and-secured by rivets or otherwise, bars of white iron t' t'. Upon the edges ofthe rocker and axle-plates are formed lugs jj, into which are screwed the straps K K, which passthrongh yokcs, as shown, and are secured by screwuluts, and thereby firmly secure the plates to their places. Upon .the under side of thc rocker-plate are formed two pins, shown at l); these pins being inserted in the stock of the. axle, prevent all end play of the plate. And upon the back edge of the axle-plate, a short pin, m, is formed; this pir passes through the inside shell o'l" the tuhlcd lplate n, attached to the axle, und in which the king-bolt is inserted; this pin'wt prevcntslateral play of the plate n.. The rocker and axle-plates I construct ot' malleable iron, as wcll as the tube-plate n, cap-f, and disk (l, by which means they receive their peculiar shape, and the inlaid bars z' z', being white iron, are less expensive than steclfyet more durable for .this purpose.

The. perch C', as also the stays D D, are attached to the axle and head-block bythe usual in eans of mortiscs and tenons, as shown, and in fullsize are strengthened by side straps, of iron. The perch C is secured to the axle by means of the coupling o, shown plainly in fig. 4, the end of the perch. being inserted in the recess in the coupling, and'is secured thereto, in practice, by bolts passing through the coupling, perch, Aand under strap l), while itis securely attached to the axle by bolts passing through the carer 7*, formed upon the coupling, and by the strap s, whichLat its upper end, is held by bolt t, while its lower end, as also bolt t', passes through strap P, thus forming, in cl'cct, a clip and yoke upon thc axle and stock, as well as securing the perch thereto. To secure the perch to the rocker, the same kind of coupling is used, which is bolted by the ears to the head-block, and the perch is secured thereto by bolts passing Athrough the coupling, perch, and strap, formed upon the rocker-plate, as before mentioned. By the use of the coupling the cost is lessened and the strength is increased. i l A The improvement in tail-board, mentioned, consists in a hollow or cellular framework, F,-which consists of an upperbar, v, lower bar o', and three transverse bars 1w w lNall makin-g :un entire casting. Any desired outline of form may be employed insteadA of that here shown.

v To give strength and lightness to this frame, it is formed of thin'facings or angles of iron, as is shown in igs. 7 and 8. And aroundthe outer edge a wider angc, of iron, marked z, is formed, which cncloses and p ro- @eci/S the panel y; this panel may beef sheet iron or wood, or both. Three plates of iron, i'l'a, :rre here shown as being placed `-across the panel, to protect it. Upon the lower edge of frame F are formed three strap-eyes b b Whichiit into the hinges c c c', upon sill d, and constitute the tail-board hinges'.A The strap-eyes b are represented as being strengthened by a slightly-projecting flange in their centre; and these atrap'eyes may be formed cellular, upon either side, or they may be made of Wrought iron, and secured to the frame. e e are brackets, formed upon the frame Rand serve to receivethe hooks of the loading-skids. f

is an eye, also formed uponthe frame F, one each side, to which chain cis attached, asshown.

To secure the tail-board in any desired position, I employ the devices hereinafter described; Premsifng that those upon the side here shown are exactly similar to those used upon' thc-other side of the body G. h'

is a shaft, passing across, under the body, and secured by boxes attached tothe sills. Uponthi's shaft are,

secured two small drums, i', formed with a. ratchet at the edge, as shown at 'q", and chains k', passing from eyes f', upon the tail-board, over the roller Z', to the drums 11'-, -form the connection .between the tail-board and 'the drums, and serve asl the-means of securing thebo'ard at any desired point. The drums Vi are actuatediby meansof the hand-wheel m', also secured upon shaft h, and by this means thechainsare let out or rolled upon the drums. Y

. To secure the tail-board in place, another shaft, n', passes under the bod-y, .and uponthis shaft are-secured two lever-pawls or catches, o', which catch into the ratohets 7" and prevent their ,revolving when acted on by the chains. 'P' is a spring, secured to sill d', and which bears against the point formed on catch p', landholds the same when thrown int-o or out of the ratchet. A handwvheel may be placed .upon Leither orhothendshot the shaft t,'as convenience may require.

1. TheA rocker and axle-plates a and h, formed of malleable and white iron, substantiallyin manneras described and shown. y 1

2. The removable diei; or die d, in combination withl the rocker-plate and king-bolt, substantially as an'd for vthe purposes specified.
